Q: What is Port forwarding ?

Port forwarding allows remote system from internet to connect to a specific computer or network service in Local-Area network.

Like you may take remote access of your home computer from any system over the internet, or share web | ftp server from home that can be accessible any part from world, remote surveillance CCTV Camera access

In the following image we can see how to take access of the home network using port forwarding.

In This part we cover how to : -

Identify IP Address (Public and Private) in Home Ethernet network.

How to access WiFi router (internet router).

How to Configure Port Forward for Remote desktop (Port 3389) in Router.

Take Remote Desktop of Home system from Internet computer using Static IP provided by ISP.

So before we start we need to know little about IP address (Internet Protocol Address) and difference between them.

Whats difference between Public IP and Private IP?

Public IP Address.

Public IP is assign by your internet service provider.

The range and record is maintain by our ISP.

We cannot select Public IP address the range is defined by InterNIC that are guaranteed to be globally unique to the Internet.

We can connect our LAN environment on single Public IP address for Internet access.

Private IP Address.

IP Address which require the systems to communicate each other in LAN network.

We can decide the IP Address | Range as per our requirement.

Its divided in 3 class.

Class A 10.0.0.0/8

Class B 172.0.0.0/20

Class C 192.168.0.0/24

Multiple Private IP Address can access internet using an single Public IP.

When we get Internet connection from ISP we only concern about internet speed bandwidth plan for home but if we want we can ask for Static IP Address.

What is Static IP Address ?

Fixed IP Address Provided from ISP (Internet Service Provider).

Example 123.52.31.91 (Fixed static).

Whenever we access internet or browse web pages the static ip will be out.

Now days every one use wifi router in home to connect multiple devices on home network for internet access, but most of people don't know the basic setting of wifi router or the IP address and access credential as the ISP provider or the system admins configure that router.

But for this tutorial we require to take access of router and configure port forward in it i am using Dlink DIR-60SL router for this tutorial.

To access the router we require to know ip address of that router and to find the ip address see the (Image 1.0) where default gateway is our router IP Address.

Now in browser type Gateway IP Address in my case192.168.0.1Router will ask login credentials user name and password, most of time the login credentials is default provided by the vendor that can be found in user manual on the other hand we can see default username and password list on website (routerpasswords.com).

Note : Before further changes its better to take backup of current router configuration.

After login most of router will display dashboard where will see the current IPS IP Setting LAN Segment and Wi-FI SSID, for port forward settings we require to search the advance or port forwarding menu in router. in my dlink router the Port forwarding is in advance tab menu its difference on every router specify vendor just search it and the page will look like following
